In the heart of Tokyo, a traditional geisha, Yumi, finds solace from her rigorous training in the art of seduction. She retreats to her private quarters, shedding her ornate kimono to reveal her delicate, unblemished body. Yumi caresses her small, firm breasts, teasing her nipples until they harden. She slips her hand between her thighs, stroking her smooth, hairless mound, her fingers finding her slick, virgin entrance. Lost in her forbidden pleasure, she doesn't hear the soft knock at her door.
